此系統是什麼
Qatar exported close to a fifth of global LNG supply through the Strait of Hormuz in the 2025 baseline. It has no LNG pipeline and no terminal that avoids the strait. Two of fourteen liquefaction trains were damaged on 18 March 2026, with repairs estimated at up to five years.
Qatar is the state in this system with the most to lose from a closed strait, the host of United States Central Command's forward headquarters, and the party Tehran will still talk to. Its exposure is not a consequence of its politics — it is a consequence of physics, and it cannot be negotiated away or built around on any timescale that matters.

- 概覽
- Every other exposure in this module has a partial remedy — a pipeline, a longer voyage, a different coast. Qatari LNG has none. Gas reaches distant markets as a liquid in a ship, and the alternative to a ship is a pipeline that was never built, so the whole of Qatar's export capability is one complex at Ras Laffan and one waterway. The Energy Information Administration recorded Qatar as exporting close to a fifth of global LNG supplies through the strait in 2025. On 2 March 2026 the complex was struck and QatarEnergy suspended LNG production; on 18 March a further attack damaged two of fourteen liquefaction trains, around 17% of export capacity, with QatarEnergy estimating repairs at up to five years. The binding constraint on Qatari exports through the war has nonetheless been transit rather than liquefaction: cargoes that can be made cannot always be moved.
- 依賴它的事物
- Total. There is no Qatari LNG route to market that avoids the Strait of Hormuz, and no capacity elsewhere replaces the volumes on the same timescale. Downstream, the dependence runs to Asian markets above all — around a quarter of Qatari LNG exports were destined for China in 2025 — with European buyers exposed through price rather than through direct supply.
- 中斷造成的影響
- Liquefaction capacity removed here is not replaced elsewhere on the same timescale, so the adjustment appears as widened price spreads between the American, European and Asian gas markets rather than as a physical shortage in any one of them. The transmission path is authored as an impact chain.
- 替代方案與冗餘
- None. No LNG pipeline, no alternative liquefaction site outside the strait and no overland route exists, and none can be built on a timescale relevant to this conflict. This is the only system in the module for which the honest answer to "what is the alternative" is nothing at all, and the module states it plainly rather than describing a theoretical option.
節點
依此紀錄撰寫時的順序排列 — 這是撰寫的次序，而非路線。
世界最大的天然氣田，位於卡達與伊朗海上邊界兩側的近海。卡達稱其一側為North Field或North Dome；伊朗稱其一側為南帕爾斯。這是針對單一地質構造、刻意不精確的概略標記。
在此系統中近海氣田，在地質上與伊朗共有。這是共有的儲層，「並非」共同事業——請見下方該紀錄本身的註記。
為何重要這是共有的儲層，「並非」共同事業。兩國分別開發各自的一側——卡達與國際夥伴合作，伊朗則獨自開發，且根據據報的跡象，產量正在下降。Vigil記錄地質事實，不建構任何雙邊安排，因為沒有發現任何此類安排：一座共有的氣田並不等於合作，若將其視為合作，便是虛構一段證據並不支持的關係。
觀察重點任一方的發展態勢是否改變，以及是否曾宣布任何聯合安排。

卡達的液化天然氣出口綜合設施，在2025年基準期間，全球接近五分之一的液化天然氣供應經由此處離開該國。2026年3月18日，十四條液化生產線中有兩條受損。
在此系統中液化與裝載。2026年3月18日十四條生產線中有兩條受損；修復估計需時最長五年。
為何重要它沒有替代方案。卡達沒有任何避開荷莫茲海峽的液化天然氣管線或碼頭，因此這座綜合設施與這條水道合起來，就構成了該國全部的出口能力。卡達能源公司估計受損生產線的修復需時最長五年。
觀察重點受損生產線是否恢復運轉，以及時程為何。

連接海灣與阿曼灣及外海的水道，由伊朗與阿曼的領海組成。在2025年基準期間，每日約有20百萬桶原油與石油產品通過此處，另有接近全球五分之一的液化天然氣出口。
在此系統中唯一通往市場的路線。
為何重要除阿曼以外的每個海灣阿拉伯產油國都必須通過這片水域才能抵達買家，伊朗也是如此。它是該區域出口經濟、以及世界出口經濟中相當大一部分所匯聚的單一節點。其替代路線所承載的量，介於它平常運量的六分之一到四分之一之間，而就液化天然氣而言，替代路線完全無法承載。
觀察重點商業通行是否大規模恢復，以及依何種保險條件恢復——海峽的可用狀態一直是由商業風險決定，而非由實體封鎖決定。
海域／海峽 · 廣域背景 信心：高 截至2026-09 在地圖上顯示 →
Ras Laffan遭到打擊；卡達能源公司暫停液化天然氣生產。同日Mesaieed電廠的水槽遭到打擊，下游石化產出因而中止。伊朗國防部報告了這些攻擊，而伊朗官員則公開否認以海灣能源設施為目標。
進一步的攻擊使十四條液化生產線中的兩條受損，約占卡達出口產能的17%。截至3月19日，卡達能源公司估計修復需時最長五年。這是有別於3月2日的另一起事件，並另行記錄。
運輸而非液化成為出口的決定性制約，貨物無法可靠地通過海峽。
S&P Global Commodity Insights統計9月有19艘液化天然氣船通過海峽，其中13艘來自卡達、6艘來自阿聯，Kpler則統計為21艘。兩個數字都是戰爭開始以來最高的月度數量，6月則為15艘。根據Kpler的數據，8月沒有可見的卡達相關液化天然氣通行。Reuters報導，許多運輸船在關閉應答器的情況下通過。這些是追蹤機構的統計，而非營運商的數字。S&P一名分析師對趨勢的評論認為，該水準至多約為戰前的四分之一。
經濟意涵
A multi-year capacity loss in a market with few short-notice substitutes changes the structure of global gas trade rather than producing a temporary disturbance in it.
仍然未知的事項
- Export volumes during the war are reported rather than published by the operator, and the 2026 forecast of roughly half pre-conflict volumes is a trade-press figure.
- The five-year repair estimate is QatarEnergy's own and has not been independently assessed.
證據同樣支持的其他解讀
- Reduced Qatari exports are consistent with the liquefaction damage and equally with the transit constraint, and the two operated at once. The record separates them rather than attributing the shortfall to either.
列出這些解讀，是因為該紀錄本身的評估並非其來源所允許的唯一評估 — 而不是對上述評估的保留。
已恢復運轉的液化生產線
Whether the two damaged liquefaction trains return, and on what timescale against the up-to-five-year estimate.
過境對照液化
Which of the two is limiting exports at a given time — they are different constraints with different remedies.
